IMPROVEMENT IN summons.

To ALL WHOM- IT MAY CONCERN; I

Be it known that we, B. G. CocHRAn, T. W. COCIIRM', and JOSElII OOCHR-AN, of Penn, in the county of Christian, and intho State of Illinois, have inventedcertain newnnd useful Improvements in Cultivators; and

i do hereby declare that the following isa hm, clealfiiand erect description thereof, reference being had to the accompanying drawings, and to the letters of referencevinarlged thereon, mokinga part of this specification. In the annexed drawings, A represents thei axl e,' havihg a suitable tongue, B, and wheels 0 0. D repre- .sents the metnllichand resting upon the axle A; nli dextending about equidistant in front and rear of the said axle. This band forms the frame of the cultivator, and upon which is supported the seat, and to which the shovels are connected. being secured upon the axle nenreach wheel, hut below the tongue on each side and passing overit, as shown.- On each side of thot'ong uc are-thesliovel-frames G G, which are connected to the hand D by ineans of the swivels Y, sothut they readily inure laterally whenever so desired. These frames G G may be of one or two pieces of metal, spread apnrt at the rear nnd held so by the braces to w. ItVwill be seen that one portion of each frame G is shorter than the other, and has each a shovel, 2', connected at its lower extremity. E represents the seat. for the driver, which-is secured upon the 'rear' portion of the frame'D by means of suitahlc brn-ccs,-nnd is provided with a metallic'plate', a,'upon each side. These plates a a are notched, a: a: :v, to receive and catch the levers F F,-to holdthc-plough or"sl 1ovelframcs as required. The levers F F are made in on L-s hape, being secured by n eansof'their pivots, .z' a, at the bend to the rear port of the frame D, while the forward ends are connected to the metal. loops 6 b, which are riveted to the shovel-frames G. By

' allowing the lovers to catch in the lovrer notch :vo'fthe seitt-pletesfea, th'e shovels penetrate deeper in the earth than when the said lovers are caught higher up'inth e sent, or the ploughs are entirely elevated above the earth, as may be desired To. each of the shovel-fi'eme stays w w therclis attached a vertical rod, H H, which'two are connected together above the axle by' the bar m, for shiftingthe pl oughs'fron right to left. The rod H being longer than the rod H extends up ncar the'seat, so that the driver, by a lateral motion-bf this rod, shifts the two shovel-frames by a single operation The'sh'ovols may be brought.- nfearer together or separatedferther by means-0f the stays;w to, which can be extracted and placed in other openings made for the purpose in the shovel-frames.

' Having thus fully described our invention, what neolai n as new, and desire to secure by LettersPatent, is-

1...' lhe metallic fraine D, ,\vit'li so'at plates at it, plough-fmmes G. G, and ploughsjz' i, all constructed,

arranged, and operating in the mhnner s ubstantiellyns and.for thefpu'rposes herein specified. I

2. The shovel-franics G G arranged iv'ith rodsH H and m, for shifting the loops 6 b and levers F F, for elevoting the shovels,- in thoj'mauncr asset forth: 4 V

In testimony that we. claini the foregoing, we jhave hereunto set our hands this 22d day of February, 1857 B. ,o. COCHRAN,
